The Parks at Walter Reed will hold a Holiday Reflection and Tree Lighting from 4 to 6 p.m. on Saturday to celebrate the holidays and commemorate the former Army medical center’s history, according to a news release.

The event — which is free and open to the public — will include the lighting of a 20-foot tree; remarks from people associated with the medical center, who will share anecdotes and discuss Walter Reed’s holiday traditions; seasonal music sung by The Marquees; snacks; and ribbon decorating, the release states. Walter Reed is located at 6900 Georgia Ave. NW, though organizers haven’t yet specified the ceremony’s precise location.

The tree lighting is one of the various community events taking place at the former Army campus as the site prepares for large-scale redevelopment. Over the next 10 to 15 years, new homes, businesses and recreation areas will integrate the site into the broader Ward 4 community.
